Error decrypting FRF

[cjhudlin]

hello,
after trying the line:
PYTHONPATH=. python3 frf/decryptfrf.py --file /home/user/Downloads/FL_4G0907217A__0038.frf i get a traceback error:

Traceback (most recent call last):
File "frf/decryptfrf.py", line 7, in
from lib import constants
File "/home/user/VW_Flash/lib/constants.py", line 99, in
class FlashInfo:
File "/home/user/VW_Flash/lib/constants.py", line 114, in FlashInfo
block_name_to_number: dict[str, int]
TypeError: 'type' object is not subscriptable

I also get this error when not entering any frf file
